ST7-220.127.116.11 Modelling Bond Slip in Reinforced Concrete
Tensile stress is generated in steel reinforcing bars via shear stress at the interface between the concrete and reinforcement. This shear stress is referred to as bond stress. If the bond stress exceeds the local shear capacity at the interface, the bar may slip relative to the concrete. This Webnote examines the implementation of a nonlinear bond stress vs slip relationship in Strand7.
